2 sa-1 Automatic Snow/Ice Melting Controller — Installation & Operation Instructions

INSTALLATION INSTRUCTIONS

1.Mount the SA-1 securely in upright position in an open space, in direct contact with snowfall pattern with a .5" (12.70mm) NPT mounting connector. The unit is water-resistant, but it is not designed to be submerged or immersed in water. Ensure that the mounting location is close, less than 2.5 ft (76.20cm) to the electrical junction box. See Fig. 4a &4b.

2.The SA-1 can be connected to the building power supply as per Fig. 2 or Fig. 3. Before connecting the controller to the electrical power supply, consult the local, state or provincial, and national electrical code. The electrical code may require a Ground Fault Protection device to be used.

3.Ensure that all pipe connections are sealed to prevent any penetration of water inside of conduit or electrical junction box.
